HINGE.

Application filed September 19, 1922. Serial No. 589,222.

To all 107mm it may concern:

Be it known that I, VARREN E. STEELE,

a citizen of the United States of America,

and a resident of the city and county of San Francisco, State of California, have invented a new and useful Hinge, of which the following is a specification. l

My invention relates to hinges, and especially to easement sash hinges.

One of the objects of the invention is the provision of a hinge for a easement sash which is applicable to a stock frame and sash without the necessity for special milling. Another object of the invention is the provision of a hinge ofthe character described which will permit the sash to move away from the amb of the frame and turn into such position that the outside of the glass in the sash may be readily cleansed' from the inside.

Another object of the invention is the provision of a hinge which is cheaply manufactured from flat stock, so that a meritorious yet inexpensive hinge is provided.

My invention possesses other objects and features of advantage, some of which., with the foregoing, will be set forth in the following description of my invention. It 1s to be understood that I do not limit myself to the showing made by the said description as I may adopt variant forms of my invention within the scope of the claims.

Jteferring to the drawings: Fig. 1 is a perspective view of a corner of a easement sash and frame to which my hinge has been applied. Sections are omitted to more clearly disclose the structure. Fig. i). is a diagrammatical view showing the outline of the hinge in planr and indicating the various positions thru which the easement sash to which my hinge is applied may be moved. Fig. 3 is a perspective view of a easement window and frame in which my hinge has been used to mount the sash. The sash is shown at a point about midway between its extreme closed and open position.

For each sash there is of course a` pair of hinges required and each hinge comprises a pair of plates one of which, 2, is provided with a longitudinally extending slot 3. A pin 4E is fixed in an extension 6 of the plate 2. The position of this pin is to one side of and intermediate the ends of the slot 3,

as will be noted from an Fig. 2.

The other half of the hinge comprises a plate 7 having an extension 8 thereon. In orderto simplify the manufacture of my hinge I prefer to make the halves of the hinge identical in outline both as to the main body of the plate and the extension thereon. A pin 9 is fixed on the plate 7 in such position as to engage the end of the slot 3 in inspection of Vthe plate 2 when the two plates lie together with the edges in alinement. Plate 7, is formed with a slot 10 extending,'in the alined super-posed position of the plates, in a direction transverse to the slot 3, and running from the body of the plate 7 out into the extension 8 thereon, Ypreferably being curved substantially as shown in Fig. 2. This slot could be straight and in a direction oblique to the slot 3, in the position of the plates referred to, but I prefer to make it in the form shown in order that the initial opening movement of the sash may be largely a pivotal one without any considerable bodily movement.

In the alined superposed position of the plates, the pin 4, which is fixed in the extension of the plate 2, engages the end of the slot l0 most remote from the slot In other words, each plate is provided with a pin fixed therein and slidably engaged in the slot of the other plate.

One side of the. hinge is secured to thev upper or lower edge of the sash by flat head wood screws inserted thru suitable holes ll formed therein. Preferably, the hinge is set into the edge of the sash so that the edge is flush with the lower face of the hinge, but with the thinplates from which I make my hinge this is hardly necessary except in work in which a high degree of accuracy is desirable.

The motion of the sash mounted on my hinge will be readily appreciated from ex` aminati-on of Fig. 2, the sash moving from the closed position to an open position in which the outer surface of the glass of the sash is accessible to one standing inside the room. Thus the window may be readily cleaned without danger to the worker. Be cause of the frictional resistance occurring between the pin and slot connection of the plates it is found that a sash mounted with my hinge, while readily moved when desired, will not blow shut or open under ordinary Conditions, in other words7 the window will, ordinarily, stay in the position to which it is adjusted. It is ot' course understood that in mounting a easement sash the upper and lower hinges must be in substantial alinement.

l. A sash hinge Comprising a pair of substantially similar plates adapted to lie in alined superposed position when the sash is closed, one plate having a yslot extending longitudinally and the other having a Yslot extending transversely of rsaid first slot, and a pin fixed in eaehplateand slidably engaged in the slot oflthe other.

2. A hinge Comprising Ia pair of similar rectangular plates each 'formed with a similar lateral extension, oneplate having a slot extending longitudinally in the body thereof, and a pin fixed vin the-extension,

the .other plate having a .curved slot in its extension and engaging said pin, and a pin fixed in said otherplate and engaging said iirst named slot.

. 3. A easement sash hinge comprising a pair of substantially similar plates', one plate being adapted lto be attached to the lower or upper edge of the sash and the other plate being adapted to be attached to the adjacentportion of the frame, and a pin and slot connection between said plates to permit a simultaneous pivotal and longitudinal bodily movement of one plate and sash oarried thereby from substantially end to end .of the adjacent plate whereby the sash and plate Carried thereby move from a position in which the plates are in superposed alignment when the sash is closed through an are of more than 90 to a position transverse tothe plane of the sash opening and intermediate the sides thereof.

il. A hinge comprising `a'pair of similar plates, each formed with ,a similar lateral extension, one plate having a longitudinal slot extending sub,stantiaglly the ,entire length of thebody thereon@ pin fixed in the extension, the other plate having a ,curved slot extending substantially the entire length of the extension thereof and engaging said pin, and a pin fixed in said other plate and engaging said irst-named slot.

In testimony whereof, I have hereunto set my hand.

WARREN E. STEELE.
